Abstract (en)
A method and network device for fast service convergence, used for communications between Autonomous Systems, includes: presetting a route forwarding table, each forwarding table item in the forwarding table includes information of a preferred route and a secondly-preferred route; setting the status of the preferred route as unavailable in the forwarding table item after a failure is detected in the preferred route; after receiving a service packet, querying in the route forwarding table the forwarding table item corresponding to the service packet, and determining whether the status of the preferred route is available, and if yes, the service packet is forwarded through the preferred route, otherwise through the secondly-preferred route. Because the failure detection time is not longer than 30ms, the switch time of the service packet from the preferred route to the secondly-preferred route may be within 50ms, thereby enabling fast service convergence.
